'Flavio Fava

The present invention relates to a composition comprising one or more (co)polymers and one or more phosphonite compounds that contain cardanol moieties. Moreover, the present invention also refers to the use of the phosphonite compounds as process stabilizers, in particular refers to the use of such compounds for stabilizing and/or reducing the Yellowness Index of a (co)polymer composition exposed to heat and/or mechanical stress.

Phosphonite compounds as process stabilizers

A catalyst composition for a polyester manufacturing process, comprising a titanium catalyst and/or an antimony catalyst as main catalyst, and either (i) at least one co-catalyst A, or (ii) at least one co-catalyst B and at least one co-catalyst C, or (iii) a combination thereof, and wherein co-catalyst A is selected from the group consisting of a metal salt of an alkyl or an aryl phosphinic acid, or a metal salt of an alkyl or aryl diphosphinic acid, or a combination thereof, and co-catalyst B is selected from the group consisting of an alkyl or aryl phosphinic acid, an alkyl or aryl diphosphinic acid a combination thereof, and co-catalyst C selected from the group of a metal salt, a metal hydroxide or a metal organyl compound.

Catalyst composition for a polyester manufacturing process

The present invention relates to the use of an additive composition for the preparation of polycondensation polymers wherein the additive combination is present in the polycondensation reaction and wherein the additive combination comprises one or more compounds of the formula (A) wherein R, R, R, R, R, R, R, and Rare independently selected from the group consisting of methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert.-butyl, linear or branched pentyl, linear or branched hexyl, linear or branched heptyl, linear or branched octyl or linear and branched nonyl groups, and Rand Rare independently selected from the group consisting of hydrogen, methyl, O(C-C-Acyl) and O&#x2014;R, wherein Ris selected from the group consisting of methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert.-butyl linear or branched pentyl, linear or branched hexyl, linear or branched heptyl, linear or branched octyl or linear and branched nonyl groups, and one or more sterically hindered organic phosphorous(lll) compounds selected from the group consisting of sterically hindered phenyl phosphonites and sterically hindered phosphites. 

Use of an additive composition for the preparation of polycondensation polymers

The invention relates to a compound of formula (I), characterised by the characteristic signals in the X-ray diffraction powder pattern measured with Cu Kalpha radiation (0.154 nm) at a 2-theta angle of 15.0 and 22.7 with a high intensity, and of 5.0, 11.3, 18.9, 20.8, 21.6 and 23.6 with a medium intensity, as well as to a method for producing the compound of formula (I) by reacting at least one isophthalic acid diester of formula (II) where R1 and R2 are the same or different and stand for an aliphatic group, with two equivalents 4-amino-2,2,6,6-tetramethylpiperidine, in the presence of at least one catalyst from the group of metal alcoholates and at a reaction temperature of between 50 and 150&#xb0; C.

Polymer additive and a method for the production thereof

The instant invention relates to polydiorganosiloxane oils having branched carbamate functions, their preparation and their use as softeners in the textile industry.
